“…Ferreira, Bock, Wilson, & Cohen, 2008; Kaschak, Kutta, & Jones, 2011; Jaeger & Snider, 2013; Reitter, Keller, & Moore, 2011). Alternative accounts attribute trial-to-trial facilitation, also referred to as structural or syntactic priming , to short-term boosts in the activation of recently processed structures (Pickering & Branigan, 1998; Traxler & Tooley, 2008); in these accounts, the cumulative effects observed in recent studies require another, different explanation (for further discussion, see Fine & Jaeger, 2016). One piece of support for the implicit-learning hypothesis comes from the observation that structural priming in comprehension seems to be sensitive to how unexpected the prime was: Less expected structures show greater priming in comprehension (Arai & Mazuka, 2014; Fine & Jaeger, 2013) and in production (Bernolet & Hartsuiker, 2010; Jaeger & Snider, 2013).…”
